摘　　要：针对1000 W的永磁风力发电机,采用电磁场有限元分析软件Magnet分析了给定的性能指标及主要尺寸下,不同的集中绕组结构对发电机空载电动势和起动阻力矩的影响。结果表明,采用24槽/22极模块化绕组方案,发电机空载电动势的正弦度高,起动阻力矩小。分析结果对小型永磁风力发电机的绕组设计具有一定参考价值。To permanent magnet wind-driven generator of 1000W,no-load electromotive force and starting resistant moment of different concentrated winding structure to generator was analyzed by electromagnetic field finite element analysis soft ware Magnet under the given performance and the main dimensions.The result indicated that 24 slot / 22 pole modular winding program can generate high sinusoidal electromotive force and small starting resistant moment.The analysis result has some reference value for the winding design of the small permanent magnet wind-driven generator.
